BLUF
A study found a 30‑minute hot bath improved blood vessel responses and lowered blood pressure more than moderate cycling in overweight adults. While not a substitute for exercise, passive heat therapy may offer cardiovascular benefits.Learning Outcomes
- Describe how hot water immersion affects blood vessel function, blood flow, and blood pressure in adults with obesity.
- Compare the immediate physiological effects of a 30-minute hot bath and moderate-intensity cycling on cardiovascular responses.
- Evaluate the potential role and limitations of passive heat therapy as a complementary strategy to support cardiovascular health.
